What this snippet does
Frozen objects silently ignore writes in non-strict mode — use for constants like config objects you never want mutated.
Expected output
3000 localhost true
Why practise typing this
Typing objects code builds muscle memory for the symbols and indentation JavaScript uses most, which prose-based typing tests never cover. DevType measures your words per minute and accuracy on this snippet and tracks the individual characters you mistype, so later lessons can target them.
